摘要

本文研究了二极管泵浦条件下 Ho :GdVO4 晶体的连续波激光特性。使用掺杂 1.0 at.% 的晶体，我们在 2047.9 nm 波长获得了 9.0 W 的最大输出功率，吸收泵浦功率为 28.2 W。此外，我们估计最大输出水平的光束质量因子约为 1.8。

Continuous-Wave Lasing Characteristics of Ho :GdVO4 Crystal Under Diode-Pumping Architecture

In this paper, we investigate the continuous-wave lasing characteristics of Ho :GdVO₄ crystal under diode-pumping conditions. Using a 1.0 at.%-doped crystal, we obtain the maximum output power equal to 9.0 W at 2047.9 nm, with an absorbed pump power of 28.2 W. The slope efficiency and optical efficiency measured with respect to the absorbed pump power are 50.7% and 31.9%, respectively. In addition, we estimate the beam quality factor at the maximum output level to be about 1.8.
